You don't need to be fasting to take this test.
When you come to the Centre Henri Becquerel for your CT scan, it's important to bring your completed examination questionnaire, your blood creatinine result and the product indicated on the prescription you have received.
A CT scan may require the injection of a contrast medium to allow better visualization of the body's organs and vessels. In this case, an access port will be placed by a technician.
All metal objects and jewelry must be removed for the examination.
In case of allergy, the day before the exam: start premedication with antihistamine. A prescription will have been sent to you with your appointment.
